Personal　Health　Record　(PHR)　plays　an　important　role　in　realizing　the　exchange　and　interaction　of　medical　information　as　well　as　in　managing　chronic　diseases.　In　the　recent　decade,　plenty　of　researches　have　been　carried　out　to　resolve　the　secure　sharing　issue　of　PHR　in　the　cloud　via　access　control　schemes.　Attribute-based　Encryption　(ABE)　is　a　promising　technique,　which　implements　access　control　by　introducing　the　access　policy.　When　ABE　is　used　to　construct　access　control　scheme　in　the　cloud,　hiding　and　updating　access　policy　have　always　been　two　research　hotspots.　However,　all　of　the　existing　solutions　only　consider　one　of　these　two　issues　separately.　How　to　combine　policy　hiding　and　policy　updating　to　achieve　secure　and　efficient　access　control　has　always　been　avoided.　Furthermore,　the　practical　deployments　of　traditional　ABE　in　the　medical　environment　are　limited　by　its　small　attribute　universe.　In　this　paper,　we　propose　a　policy　hiding　and　updating　ABE　(PHU-ABE)　based　on　the　Fast　Attribute-based　Encryption(FAME)　to　tackle　these　challenges.　We　argue　the　security　of　PHU-ABE.　The　experimental　results　demonstrate　that　our　scheme　not　only　protects　users＇　privacy　but　also　realizes　efficient　policy　updating.
